Florida wildlife officials suspended their search on Wednesday for the alligator that dragged a two-year-old boy into a lake by a Walt Disney World hotel in Orlando, adding that they are "confident that the alligator responsible for the attack has been removed."

"This conclusion is based on expert analyses and observations by staff with extensive experience in investigating fatal alligator bite incidents," the commission said in a press statement. "The conclusion took into account the proximity to the attack site of removed alligators and witness descriptions."

A total of six alligators were removed throughout the search.

The conclusion of the investigation comes more than a week after Lane Graves was dragged away by an alligator into the manmade Seven Seas Lagoon at Disney's Grand Floridian Resort & Spa.

The boy and his family – parents Matt and Melissa Graves and a 4-year-old sibling – were visiting from Elkhorn, Nebraska.

"There's a sandy beach area and the family was out simply relaxing," said Orange County Sheriff Jerry Demings. "They were wading at the water's edge when the alligator attacked the child."

The toddler's father struggled with the alligator to try to save his son, "but was not successful," Demings added. The mother also went after the boy.

The family then alerted a nearby lifeguard that an alligator had attacked their child, Demings said.

Video from the hotel showed guests watching the fireworks show as a helicopter searchlight hovered nearby on Tuesday night.

The hotel is on the waterfront of the lagoon, which also borders the theme park.

Nick Wiley, the executive director of the Florida Fish and Wildlife Conservation Commission, said that Disney routinely removes alligators from its property with help from the commission.

“There are no words to describe the profound sadness we feel for the family of Lane Graves,” said Wiley. “We will continue to keep this family close to our hearts as they deal with the pain and grief of the loss of Lane.”

The commission said alligator attacks are a "very rare occurrence" in Florida. It was first such incident at the Disney resort in all its 45 years, said Orange County Sheriff Demings.
